# Launch...
# (1) launch the docker container
# (2) start a bash there to process a bash commandline
# (3) this commandline in turn launches an interactive bash
# (4) and this interactive bash gets a startup-Shellscript to perform
# (5) and this shellscript is read from an temporary named pipe to another shellscript
# (6) which in turn prints the script code from the setup-variable $COMMANDS
#
